Froome never doped like the other guys, and his anomalous salbutamol finding was shown to be very flawed by an actual scientific study (I guess this forum has its fair share of anti-science conspiracy theorists though)
His performances weren't that abnormal either, not compared to 1990s and Armstrong, and now Pogacar and Vingegaard.
So yes you're correct that it's obvious with the huge time trial wins of Pogacar and Vingegaard and other performances which haven't been seen since 20 years ago that something is amiss. But this constant comparison with Sky and Froome, Thomas etc with their modest performances is just crazy, irrational and simply makes this whole forum the joke that many outsiders consider it is.
Irrational unscientific lunatics with nationalist agendas mostly, rather that sensible considered rational/scientfic arguments about the evidence before us.
With regards to Froome & Sky, it's all relative, i.e. relative to their rivals of that era.
The salbutamol was the tip of the iceberg (& absolutely doping, aka something others were suspended for). If whatever cocktail Sky had was good enough in the 2010's to smash the peloton, then it's all they needed.
If current stratospheric performances from Pog & Vinge make Froome & Sky look like amateurs by comparison, it's simply evidence of an out-of-control arms race constantly pushing the boundaries forward. We know this because Jumbo & Vingegaard have just supplanted Pog & UAE in a similar manner within their own little duel, i.e. when applying your logic re Sky, Vingegaard made Pog's LPDBF 2020 look "human" compared to what he achieved on Tuesday.
It's escalation.
