So trying out changes to a platform isn’t a bad thing and can lead to a lot of good optimization, but usually you don’t just push them onto the entire user base without testing/marketing research to try and anticipate their effects.

How exactly do these changes make it to production without being evaluated? I know blame is mostly on Musk here but do the software devs really never stand up and say “we’ll look into it and get back to you in a few weeks”?
