to be fair, wikipedia is still excellent for a lot of things. technology, science, mathematics, geography, whatever you want to know, it's there. as a general rule: the further removed a subject is from anything that is politically or ideologically charged, the better and more reliable wikipedia will be.
even for politics-adjacent topics you can find tons of good info there. geography, economics, business, history, etc - you just have to exercise constant awareness and vigilance. if you know how their brand of propaganda generally works, it is easy to recognize it when you see it.
