Some people like it because they thrive on attention and being disruptive, and open offices are optimized for that behavior.
and that's perhaps only technically true... as soon as you start adding quiet spaces, collaboration spaces, conference rooms, etc. necessary for open office layouts to actually work, the plain 3-4 person office plans (which nobody had for years, i was lucky to have them replaced with open office only during the pandemic) are just plain more efficient. open offices, to the surprise of no one actually working in them, force people to the worst of both worlds: have to commute to work to IM with colleagues anyway to not disrupt the whole office. it's madness.
But in the era of WFH the cubicles and private offices make even less sense: if I spend most of my day isolated in a cubicle, then why can't I spend that time in my office at home?
Private-sector politicians and frat boys love open-plan offices; most of us are neutral at best, and with age most people come to loathe them.
Not sure what a "Private-sector politician" is, nor what your intense hatred of open-plan offices has to do with collocated workplaces in general, but I can assure you that the reasons people split across the remote vs. office spectrum is far more diverse than your generic bucketing of "white male jerks == office love; everyone else hates them".
It's kind of ironic that someone has such polarized, uncompromising views on the topic, supported by the reasoning that "they don't reflect and support a diverse and non-binary workforce"
There are plenty of more substantive reasons to not want to go back beyond "it's not fair".
