I don't think so. Don't see how that would make sense, personally.
The game has - from a general point of view - a good reputation among the people that have played it.
If you care so significantly, don't you think that it might be interesting to consider the actual full game that is available right now?
I think what they mean with the game becoming a service is that the basic PS+ Edition will be free for everyone (no PS+ required) and that you'll be able to upgrade to the standard complete edition and that you'll be able to purchase additional expansions if you want even more content.
Definitely a bit of an annoyance and not so nice, but I wouldn't say it's unacceptable if they're clear with the communication.
Delays happen. Video game development is not a 100% foreseeable and predictable process. (well that's the case in many engineering and software engineering fields, and others) Definitely a bit weird that in this case the full version of the game is out and and stripped-down version is taking a long time, but yeah I think the reasons behind it make sense. It's understandable that they want to prioritize that the game is 100% functional for the full version; for people who bought the game and spent money and therefore avoid potentially overloading the servers by releasing the PS+ Edition.
Anyway, you can always buy the game right now if you want.
?
If find it weird that you considered yourself hyped for a game that you apparently didn't want to purchase? Surely if you were at the point of being 'hyped', then you were probably interested in the game enough that you'd consider it worth purchasing? (And if you were hyped, then I assume you probably estimated the likelihood of liking the game being pretty high)
Also, they're working on the server performance and netcode. It needs to be able to perform very well with a very large amount of users. Giving the full game away isn't going to change anything. They need to be able to handle the player count and server traffic and they're working on that. So they aren't wasting resources I'd say.
