I really regret buying GTA V. The fact that they don't allow unofficial multiplayers and force us to play on their catastrophic GTA ONLINE makes me puke.
They say they love mods, except those that negatively affect the multiplayer experience for others...
FiveM and such clients are offline modifications 
Ofcourse I regret it, because:
1) I do not get to play it anyways since I changed my computer to an incapable one
2) FiveM are an exception that is at risk of a legal action
3) Rockstar has actively issued legal cease and desist threats to several promising multiplayer modifications that were forced to shut down as a result.
I do not see how an external client makes someones experience online inferrior. They simply hate the fact their shitty multiplayer is being challenged.
Does that opinion make me think that GTA V is worse than GTA IV? No.
In other words, you should, as usual, stop talking smack when you've no idea what you are talking about.
