There are limits to the amount of due diligence companies should have to do to ensure that people know they are clicking on ads. Anyone who is interested in avoiding clicking on ads will easily identify Google's, or not see them at all via a software solution. For the rest, there's not much short of an acknowledgement overlay that will get the message across reliably (for text ads -- image ads are easier, but google doesn't have them).

There are also limits on disguising search results as ads.

Really? Just increasing the contrast or adding a border around the border or using extra spacing as a separator or another separator can help a lot. But it's hard to make changes that hurt the bottom line. Changing it the opposite way is much easier. Google has a lot of UI and UX experts and I don't think the changes are accidental at all. In fact, they must be very carefully planned.
Edit: Found an old screenshot where the difference is much more apparent.
Basically, clutter up the page more? Facebook has no background, nor do Yahoo! (front page) or Reddit (sidebar). Bing's and Yahoo!'s SERPs and Reddit's sponsored link are near Google's in terms of contrast and signage. Although Reddit opts for a border but conflates ad space with space that is used to promote results algorithmically, because it's not sufficiently confusing I guess. In terms of HN darlings, DuckDuckGo is actually worse (approximately the same contrast, "Sponsored result" doublespeak rather than just calling a spade a spade). You're asking Google to follow a standard of behavior that none of the other major sites I visit reach.
In terms of industry norms, Google is about as good as it gets. Maybe you feel that's not enough, and I guess that's a qualitative judgment that you're free to make. People will differ on things like this occasionally :P. I'd ask for some kind of harm analysis at the very least before I accept that there's anything untoward going on.
