Politics is no longer separate from science.
When has this not been the case? I mean, back when politics and religion were one and the same, they literally murdered, banished, or imprisoned scientists under the guise of “heresy”.
Not under the guise of heresy but for heresy. And they understood the risk of making themselves look like fools and backed off quickly.
Then natural sciences became free of political bullshit for a few centuries, because people saw that there is "something" to it and that meaningful progress is being made which results in undeniable and objective technological development. Even the Vatican runs their own astronomical observatory.
Then somebody invented the concept of "human science", which is an antithesis of both "human" and of "science", and the rest is history.
Universities have become breeding grounds for political activism.
Aside from the fact that political activism has always been one aspect of academia, since both academia and politics exist in the same universe, I don’t think there’s actually any evidence to support claims of this being more so now than in the past (as the wording “have become” implies).
Political activism was not the motivation of Galileo, Newton, Faraday, Pasteur, Darwin, you name them.
Today actual science happens in commercial R&D labs while public academia degenerated into something like the lowest chamber of the parliament.
I don’t think the skew has moved at all. Again, look at the history of politics and activism in academia and it’s always been on the left, often far left (far more left than today, in many cases). The loss of academic freedom thing is orthogonal to this — that change (which I consider to be negative) can happen without any change in the typical political slant. (Which, frankly, is just innate in education anyway, since secular academia is all about studying objective reality: as they say, “reality has a liberal bias”.)
OK, but "the left" apparently stands for such a diversity of ideas as eugenics, scientific racism, cure-all lobotomy, nuclear weapons research, gay therapy, cure-all gender affirmation, critical race theory, neolysenkoism, etc. - it's hard to even define what "the left" really is

Further conflating "the left" with liberalism isn't helpful either.
