Many of them are either exceptions made by Google through shady deals or apps that were overlooked by Google before they published the app.

The Galaxy Store was a special exception made for Samsung. Generally, Google is pretty "persuasive" about being the only pre-installed app store on the phone.
Even something as simple as the Wikipedia app checks to see if Google Play Services is installed and running before it'll let you use it.
Yeah, the Kindle app pretty blatantly tells you why they removed in-app purchases.
They can try selling me their Premium subscription again when they start suggesting more than one or two videos (if that) on their homepage that actually interest me.
Not that I'll ever pay for it, anyway. But get me something that I'll actually click on to get served ads before trying to sell me something to get rid of them.
I apparently misremembered. There was a poll, and they posted the results here. But the poll didn't make mention of Lemmy and instead asked about migrating entirely to Discord (which honestly makes sense since the weekly thread is mainly a "live chat" of sorts). They voted to stay on Reddit instead of migrating entirely to their Discord server.
Both the subreddit and Discord server are active enough that they don't feel "barren" but small enough that they have a tight sense of community.
I'm not too interested in being a moderator. I don't have time for it.
As for migrating the community, they actually are one of the communities that held a vote, and they voted to stay on Reddit rather than migrate to Lemmy. I'd like to respect that decision.
I don't have any problem with content being mirrored, though.
It's /r/Toonami. It's gotten about 35k members over the years, but it's not as active as that number might imply.
I'd argue that, for Lemmy, it depends on which communities you subscribe to. Even if you subscribed to one community that now has stuff you don't like, there's a decent chance that another community on another instance has what you're looking for.
I used to use Reddit a lot more back before the whole API fiasco earlier this year. After that, I stopped, save for posts promoting Lemmy and one very specific subreddit that never migrated to Lemmy and that I just couldn't go without. (The other subreddits I could either do without or were already replicated on Lemmy.)
Ironically, my Lemmy app (Boost for Lemmy) likes the regular URL but doesn't like the !link (or whatever it's called).
And, yeah, it loads the community in the app, not in a webpage, when I tap on it.
It's more that Epic added their own payment system to the app (and offered, IIRC, a roughly 30% decrease in Vbucks price for people who opted to use it instead), Google and Apple both responded by removing the app, and then Epic sued them both and even aired a special presentation in Fortnite. All in the same day. Epic intentionally did this.
