So the claim is that said suppression was time-limited and no longer in effect?I'm sorry but your current search is not meaningful. The article is from October 12, 2020, and any suppression would have long since expired by now.
Where is the evidence to support this claim? Nobody took screenshots? Nobody contrasted it to literally any other Google search?
I can search for a literal TypeScript error that is generated by a popular library, and still not get the definition for that error as the first result. That doesn't strike me as evidence that Google is suppressing the definition of the error. This is something I do a lot, too. I have years of experience as a developer using Google to get information I want. Even with a brilliantly-specified search, for a popular thing, the result I want being first isn't guaranteed.
