I think it's less, "We're worried people will flock to Firefox," and more, "We could get in a lot of legal trouble for trying to force everyone onto Chrome".
I've used multiple different distros before and after, all Xorg, and never encountered similar problems. There were bugzilla reports for the Firefox issue I had, all of them attributing it to Wayland.
I used KDE with Wayland briefly a few months ago. The right-click menu would look very glitchy. Items disappeared until hovered over, and then disappeared again when moving the mouse. Firefox also had some issue where it would only take half the screen.
I despise Discord. It's an information black hole. Everything is closed off, unindexible, unscrapable, borderline unsearchable. If someone posts something useful on Discord, good luck finding it after a few months, let alone a few years. Meanwhile, I can find forum posts with useful info from over a decade ago. If Discord the company dies, everything on the platform dies with it. There's no internet archive for Discord.
It has a place as a chat app, but its use goes far beyond that. Some subreddits used it as a Reddit replacement, companies use it for tech support, and entire apps are built around it (eg. MidJourney).
It's not unusual to have big stars in movies. There are movies full of nothing but A-listers. It's been the norm since before any of us were born. However, I find there are some big actors where their presence overshadows their character (if that makes sense). I do tend to enjoy movies with smaller actors that I haven't seen quite as many times already.
I'm not really a fan of real A-list actors' faces in games. Inspired by real faces? Sure. I know the term "immersion" is mocked a lot, but few things force me back to reality than seeing Hollywood megastar multimillionaires in my fantasy world.
