If they really had a problem with it they would not hit like on the art, as it's entirely in their power to ignore stuff like that, also yes it gets them views and that's why they often play into ships and fueling artists. Part of my whole point is that it's not that serious usually, Vtuber shipping and honestly shipping in general is at it's best when it's not taken that seriously, and is just a lighthearted fun thing. Unless the Vtuber takes direct issue with it I just don't see the harm personally.
I do understand that some people think Vtuber shipping is weird and they don't like it, that's fair, I would say at that point Black-List the "Virtual Youtuber" tag on here, and other tags such as Hololive and Nijisanji. Block/Mute the artists on social media such as Twitter.
