I really can't blame them entirely. Perhaps you could blame companies for not using a hybrid model where players can host privately plus maintaining their public servers.
Why? Because in a similar vein to how social media needs to be moderated to prevent the bad apples from spoiling the bunch, games now need to be moderated to maintain reputation among the community. If a player hearing about CSGO for the first time has no idea what they're getting into finds only a public server running 24/7 CS_OFFICE with Warcraft Mods they might get a bad impression of what the game is. Having consistency in user experience is highly important, and public servers being maintained and moderated by the developer is probably the most important part of that. What about all those servers that have massive latency issues? That's a bad look on the game because most players won't recognize community run servers are the reason the game behaves buggy.
Do I dislike it? Yes. I think it has created irreparable harm to the ability for gaming communities to build organically but so long as central hubs like Reddit or Discord continue to pop up I figure they've just offloaded the community aspect to external sources. Is that better? I'm not sure. Partially yes. Losing contact with a friend because they stopped logging into your preferred server isn't really a thing if you're Discord friends or Steam friends.
As long as there's a clear UI separation, there's no harm in providing both first and third party servers for brand perception & user experience. A similar issue is content provenance. In StarCraft II, for example, official maps and custom maps live in separate tabs. No one expects a Dragon Ball-themed map to be made with the same standard as an official Blizzard map.
I suspect it's simply to control monetization and without the extra engineering cost of private server releases.
