WeChat works because it is government-backed and I don't really see how Twitter can morph into WeChat without an authoritarian regime controlling it, promoting it, and stamping out the competition. Having a simple tool for publicly posting snippets of text seems like a useful thing for a free society though and people are still using Twitter because it still mostly serves that goal. People are highlighting every substantial change because each change moves the needle to where it doesn't serve that purpose for some. Although it's not a hard line and even when it becomes unfit for purpose, it may be better than nothing and also it may be hard to stop using it (you may have a job that involves posting to Twitter, and you can't stop posting to Twitter until you find somewhere else to post.)
