Electronic Frontier Foundation survey hosted on Microsoft servers

Today I received an invitation from EFF to fill out their survey. I was shocked to see that it's hosted on Microsoft servers. Someone on reddit opened a discussion about this too (title link), criticizing being subjected to Microsoft ToS.

I opened the survey to see just how privacy-unfriendly it really is. This is what I found:

The survey asks very ad-relevant questions such as age group, gender, race, education, housing, INCOME!, employment, etc. And then they ask questions that are very relevant to Microsoft platforms, such as where I read my news, what social platform I visit, etc. And to finish with a bang, they ask my political affiliation.

How could they do this? Is there no supervision/review in EFF? Were they paid or was the survey author corrupted by Microsoft?

I guess it could have been worse - hosted on Google servers...
