She (similar to Reagan in the US) enacted a massive shift in government/society from a more social-democratic focus to a more (economocally) liberal one. Her big goals were to privatize and financialize as much as possible.
This ended up leading to (as it always does) massive increases in inequality, with particularly rural/industrial regions suffering heavily while the services/financial sector in London boomed.
So she is EXTREMELY polarizing. Many conservatives or big-business types worship her, while for many/most others she’s seen as the worst thing to happen to the UK.
I use opensuse (tumbleweed and slowroll) because I just wanted to try it out a few years back and it mostly just works.
If I were to reinstall today, I’d probably use fedora again, since it’s much easier to use things like Waydroid.
