As a professional online marketer who does search engine optimization, I disagree. These trends represent what people search for, not what gets displayed as a result.

It wouldn't make any sense to censor some and leave the sharp spikes. My guess (11 years in business) is that Google doesn't care that this is showing. It's not in the news and I haven't seen it on any major meme platform.

The simplest explanation is that the sharp spikes could be caused by the sudden influx of cardiac arrests after a couple of months after the vaccine... ehm... gene therapy... rollout in various countries.

I could be wrong and by all means, there was plenty of censorship and suppression, but I'd say that this is a correlation, not proof.
