One concern I saw mentioned was that after receiving advertising revenue, Wikipedia might become reliant on it, which would allow an advertiser to exert influence over the organization, such as demanding for articles to be removed that are negative to the advertiser's interests, with a threat to pull advertising funding.

But yes, I agree, it seems possible for WP to accept advertisement without compromising on its core values. Decide in advance never to give in to such demands, and do not take the funding for granted.

Deciding not to accept advertising might be short-sighted. With enough years of advertising revenue, Wikipedia might be able to work toward financial independence (where returns on investment exceed costs), and build an endowment like the sort that powers top universities.

They could set up a separate non-profit organisation (that donates its proceeds to the wikimedia foundation) to sell and manage the ads. Place the organisation in a city far from any wikimedia presence to counter casual contact. Put in the charter than there can be zero personnel overlap between the businesses at any level and that nobody at the ads company is allowed to edit any article on wikipedia or any reason, much less hold any admin credentials . Embrace openness: Publish as much as is practical about every deal, and make sure all ads on the sites are directly referenceable back to the deal in which they were purchased. Publish the names and resumes of all account managers.

... if they can get by with donations, that seems a tad simpler.

Also, I don't have to watch any ads! Hurray for Wikipedia!

You seem to have missed the bit where they ran massive, obnoxious ads for months begging users to donate. And all for a pittance in donation revenue.
