That’s not a new or good, cogent argument. It’s essentially the same argument - “It’s tradition, it’s always been that way”. And that’s not a reasonable or rational answer as to why it must stay that way.
August - May is for safety? So would an October - July season be unsafe? What would make an Aug-May season more safe than a Oct-Jul one, for example?
Changing the season schedule is something that would absolutely need to happen anyway, even without the CV19 issue. A change to the traditional Aug-May season is categorically going to happen as the upcoming World Cup is being held in December.
August to May is not “popular”, it’s just the only frame to which a season has been run in living memory. Popular would imply its the most liked when compared to other time frames. No other time frame has yet been tried.
It’s unreasonable and massively fanciful to assume that fans would turn their backs on the game, both in terms of matchday attendance and home viewing, in any number, let alone numbers sufficient for sponsors to be able to command reduced deals based on an October - July season, rather than the current August - May season, for example.
