An ideology is just a system of a system of ideas and ideals, so every institution or structure is ideological. The same with an agenda. That can include figures such as Thiel funding Polygenic Scores to push a particular perspective, or institutions declaring their adherence to certain DEI policies.
Universities are complex organisations with many - often competing - agendas and ideologies sometimes tied in with funding, sometimes with adhering to other imperatives, as well as competitive and sometimes resentful individuals who have a stronger sense of individual autonomy and agency than employees in other organisations (that's well-documented). We've all seen press coverage of what happens when the tensions between academic freedom/insitutional ethos or agenda/freedom of speech reach breaking point.
If you look at any university's mission statement, or even the ways academic awards are described you'll see that changing society and what might be thought of as EDI are frequently mentioned. For example, for a doctoral award in the UK, graduates are expected to 'build relationships with peers, senior colleagues, students and stakeholders with sensitivity to equality, diversity and cultural issues.' The National Framework for Qualifications in Ireland describes one outcome of doctorates as 'Scrutinise and reflect on social norms and
relationships and lead action to change them' - the UK has something similar as it's in alignment with EU awards.
What it means to 'educate' students or what it is to be an 'educator' is continually shifting, so I don't think there's any common sense or consensus on what that actually means.
I do think everyone should be attentive to who or what organisations/networks fund or have influence in universities, and ignoring the role of Thiel (in this instance) is in itself to adhere to a particular ideology or agenda. We're creatures of our environment including the news/media environment and fundamentally hard-wired to find certain narratives exciting or unusual, or to be attracted to ideas of the truth, villains, heroes and so on but as adults we also have to follow the money, accept our own biases, and not be stimulated into a mob mentality.
