“Don’t let perfect be the enemy of good” Nobody’s forcing you to use the “official” join mastodon site - it’s not a keystone of the fediverse. And not to be dismissive, but you made a PR and someone didn’t follow up with you? Nobody owes you anything in life, including a response to a PR. People get busy or just don’t even want to respond for no reason at all - learn to deal with it in a graceful way.
History lesson
WebKit is only open source because its a fork of KHTML, originally developed by the KDE project [0] for the Konqueror browser [1]. KHTLM was developed under the GNU Lesser General Public License (LGPL) [2], which limits companies from taking the hard work of open source projects and claiming them as their own without giving back to the community.
If Apple’s surprising you with the “open code” released under the WebKit project, it’s because they’re legally requried to. We can thank the Free Software Foundation’s LGPL for that.
