"In the simplest terms, Profit and Sustainability Rules — or PSR — allow clubs to lose £105 million ($134m) over the course of three seasons, or £35m per season, on a rolling basis."

Just curious, if those values are anywhere near correct; how is it that same PSR questions aren't being asked of Arsenal, Villa, Bournemouth, Brentford, Chelsea, Palace, the RS, Spurs, West Ham?
What other factors, if any, are at play here?

(I am aware that Everton's deductions included results for seasons prior to 20/21).
