So after fighting only a little to avoid the characters limit I sent:
The mess caused by vendor prefixes on the wild is not enough, so we have new -apple webkit.org/blog/3709/using-the-system-font-in-web-content/ @jonathandavisI'm not gonna copy each following message and reply as you can try to read it there, but I would like to point out some parts, a better explanation and say thanks to everyone that contributed as I think that it has helped to talk about the problem caused by the current usage of vendor prefixes.
I'm nobody, I don't work on a big company, I haven't written any book, it takes me too long to write things because I have to try to find the correct words so excuse me if this post has mistakes or it's unreadable, I've tried my best.
What did caused me to send that tweet?
It's known since quite some time that the current usage of vendor prefixes is causing harm in the interoperability between web browsers. Quite a few years ago we had the first browser wars between IE and Netscape where each one tried to defeat the other introducing new features as fast as possible and we all know that IE6 was the winner, so we had so many websites that took advantage of those proprietary features and the "Best viewed with IE" or "You must use IE to view this site" messages that most of us hated with passion.
It took many years to fight and reverse that situation, engineers had to work too many hours finding out the way that things worked and reverse-engineering the specifications. We also keep the perpetual "Mozilla" and "like Gecko" in the User-Agent, but currently this is absolutely getting out of hand.
So going again to a browser monoculture is something that I don't want and anything that points in that direction makes me cringe.
Currently other browsers are trying hard to avoid those same mistakes, experimental features are available only in "Nightly", "beta", toggling a setting in about:flags, using a command line parameter, whatever, ... but the common goal of that approach is to not expose experimental features for broad usage to the public web but the people that want can try it out, give feedback and find out if it solves the problems as expected.
But Apple is not planning to do that, they pointed out that this isn't aimed only at betas (although a day later he replied that it's only in beta at the moment, obvious as there's no final release ATM).
And one part that I found really offensive was this tweet about my comment that Apple doesn't remove the prefixed version of anything that they introduce:
And we will always support them (unlike some vendors that remove things at will). So what is the issue?with other comments that I found ... we'll I think that it's better to not say what I'm thinking:
You can’t just break sites or apps. Apple doesn’t roll like that. A number of properties changed from prefixed to unprefixed too.
It is what any company should say that cares about developer and user experience. An API is a contract and guarantee.Just load the Release notes of any Mac OSX version and search for Deprecated Frameworks and Removed Frameorks.
So it's clear that Apple is able to deprecate and remove APIs even if they were the greatest new innovation at the time, but the obvious difference is that they have full control of the OS (if you don't like what we do, here's the door out), but on the Web they are playing the Embrace, Extend, ... game.
Going back again to the starting point:
Why are vendor-prefixes bad?
I'm not the one stating that, please read carefully this great post by Karl Dubost, take a look at what Mozilla and Microsoft has been forced to do just to have a chance of people using their browsers, and then tell me if this message from @ryosukeniwa is right or wrong:
I don't think proprietary CSS features aren't that bad since they fallback nicely. DOM and JS API are different, ..But as I said, I'm nobody, please read what Daniel Glazman has to say about the matter. I'm really honored thinking that all of these great people have spent some time reading about my humble tweet, but then I have found out the real reason why I despite vendor prefixes: The CSS working group asked all of us to stand against them for the Open Web and it seems that the message got deep into my head.
That's enough for this post, I have many other things to say because there were lots of tweets and I don't want to mix the things here.
