FROOT was more interested than previous owners on profitability, so he probably would have been in favor of more users regardless of where they were from. As long as they didn't endanger the site's legal standing or give enemies a casus belli. However, he was also one of the more openly right-wing leaders of the site, so it's hard to say if it was due to intentional policy decisions.
The entire soyjak character was a mockery of Libdummys. Old soy lore was very heavily derived from covid-era politics (eat the bugs, IFLS, vaxx). People use this same cope when talking about the 'cuck I've noticed, although it is more true in that case. It is true that original soyteens made fun of all politics but that wasn't because they didn't have political beliefs, it's because they could joke about their own side too.
