It's surely not difficult to see that the statement "since CoronaVirus deaths stopped being sky-high, flu deaths outnumbered Covid deaths" is a textbook example of cherry-picking. The only way that would make sense is if you believed that Covid-19 deaths are not going to flare up again. Time alone will tell if that's true, but the sad fact is that the rise in cases is inevitably going to be followed by a (delayed, and hopefully not too severe) rise in deaths.
In terms of the original post, rather than spinning some conspiracy theory, part of the reason these questions aren't asked is because some of them already have answers:
1. As I've pointed out, the rise in cases is not attributable to a rise in tests, based on publicly-available data that you are free to check yourself. So there is no need to ask this question: more people are contracting the virus now than in July/August, although probably still fewer than March-May.
2. The efficacy of masks has been under debate (including on AB) since March, so it's not a novel question.
3. The comparison to flu has also been made for months, and remains invalid: Covid-19 spreads faster than flu, kills more of those it infects, and seems to have longer-lasting impacts among serious but non-fatal cases.
