Well, it was the users that were against it from the beginning. Staff were concerned. Management and shareholders were the only ones celebrating it.
Management are obliged to look out for the shareholders best interests.
Actually many of the users were for it, who are tired of the one sided moderation and censorship.
I just heard a good thought about what's the real problem with these monolithic social media platforms, that includes twitter, youtube, etc. That their database is not searchable, the users get served something by their algorithms, and the algorithm is not fair, or open. What, you say youtube has a search function? No, that is not a search function, that is a highly censored and curated list you get served disguised as search results.
Youtube search has been useless for years in my experience, it tries to serve me irrelevant stuff or worse the exact opposite of what I searched for. Because it is weighted to favor videos generating more ad revenue. So you don't get results from low view but potentially relevant videos, you get served spam and fake content by it that has terrible user approval rating.
It is actually so bad now, that there are fake channels uploading bot generated content and it gets traction by youtube.
If youtube was to serve users it would not have hidden the approval rating of videos, and it would not put restrictions on search results. And it would promote all content equally and fairly.
And this last bit was the hope of most users for Elon buying twitter. To get a fair and unbiased playing field out of it. Now I imagine twitter staff is doing the exact opposite of that frantically to engrain the censorship and bias even deeper, so even in case of a hostile takeover they couldn't get rid of it that easily.
