I literally just installed Playnite as a means of organizing both all the games that I have gotten through the various storefronts over the years (thus meaning that I have no particular reason to favor specifically using the steam launcher over any other, and in fact have used this to remove games from my active Steam library and replace them with, say, the GOG versions). In that sense the Steam client offers nothing to use over another service, though for games to play I still need to be logged in with the program opened to launch some of them.
As regards the question of moneyhatting devs, I'd like people to remember that in the earlier days of Steam and Origin the companies involved did about the same thing for exclusive game distribution, as I posted in the thread about that non-infringing XCom game:
My concern is that when people say things like "Well, this would be acceptable if it was their own IP involved" just means that they've gotten normalized to the same thing EA did with Origin -- outright buying out the companies that produced the games they wanted to have sold on there.
The idea that doing so represents a better deal for the end user in any way is absurd, since right now the Epic deals aren't exclusivity for these games in perpetuity or controlling stakes in the studios themselves. I don't expect to ever see Burnout Paradise Remastered on Steam, even if the first game was.
And don't forget about how Valve acquired the team from DigiPen that made Narbacular Drop in order to create Portal, the game that got the most critical praise out of everything on the Orange Box -- which you needed Steam to run on PC. I don't think anyone has to like EGS (especially with their privacy-violating antics) but the fact that this sort of exclusive distribution rights matter was an important step to how all these companies have set up their distribution stores can't be ignored, and I'm tired of lazy sarcasm about competition that brushes aside this history (which isn't a criticism at you, @oni-link, to be clear, just the general shape of discourse around here).
Where I am given pause is in the discussion about what data the launcher gathers, and how the service uses it. I've had the launcher installed for a while in order to do Fortnitey things, so it's probably too late for me anyway. Nonetheless it's scummy enough behavior couched in such weird defenses that I don't feel comfortable recommending the program to anyone. I would make a GDPR complaint were I a Eurozone person, if only for the dark-patterns they use for communication registration (i.e., receiving e-mails) let alone what the program does even when no selection for sharing information is made. This bothers me much more than guaranteeing a payout for devs they want to put their games the service, since the former -- while by no means a
good thing -- is one that the entire industry, indeed most industries under capitalist systems, engages in.
