Google has removed features that it had 10 years ago.
I do suspect the main thing people complain about currently with Google is the abundance of ads and the algorithm that has encouraged stupid amounts of articles of a certain length. Recipe for baked potatoes is now 2000 words long.
Greater scale = greater cost of keeping data hot in their search data-warehouses (esp. in light of contention over memory/caches.) Keeping around both a source-text string and its tsvector representation (or whatever Google's version of that is) is a "thing that doesn't scale" that they could provide at 1B queries/day, but probably not at 10B queries/day.

That's not the algorithm's fault per se; that's instead the fact that recipes can't be copyrighted, and so these sites can freely steal + repost one-another's recipes, and so you'll find the same recipe word-for-word on many sites, thus making an exact match in the recipe part not contribute highly to ranking any particular site. The 2000-word blog post, on the other hand, is actual Intellectual Property unique to the site posting it. So it only appears in the one place; and so when your query matches it, it ranks quite highly indeed.
Yes, it is. There are good recipe sites out there with authoritative, reliable content and fast loading times. Google says it prioritizes those things, I can identify sites that have them, and yet the algorithm doesn't favour them. That's the algorithm's fault no matter what memes about copyright law cause a proliferation of shitty websites.
Control. They've moved from helping you find what you asked for, to trying to influence you to changingnwhat you ask for to the thing that paid them the most.
Similarly they're they're forcing creators to alter content to match their metrics or fall into obscurity.
