To be honest, there are several reasons as to why I'd be opposed to Qatari ownership, with many already stated.
However, if we do end up getting bought by the Qatari, there might not be as great of an issue as some suspect. The biggest being them using United to push their politics
If we do look at PSG, what QSI has done is inject money to give some sort of identity to a club that (lets be honest) didn't have much of one to begin with. What they chose was to be associated with luxury and expensive high-profile stars.. Without pushing any politics of promoting Qatar nor their views on the LGBTQ+ community. Last year they even played with the rainbow flag on their backs.
This doesn't change where the money comes from, nor how it has been earned (on backs of people where human rights have been broken).
But if we do get bought, this is what I hope/expect to see.
United already has an identity, a strong following and is the biggest brand in world football. I don't see them messing with this, there is history, emotion and passion that they could only dream of in PSG.
Local community is a big part of what makes United great, given the promise on investing in the facilities, I hope this will extend to the people living in the area.
Build on the probably only good thing to come out of Glazer administration, which is commercial sponsor success allowing the club to more or less be self sufficient.
Silent ownership akin to what is going on at Newcastle.
