Honestly, affinity is just a company. They will make a Linux version if it makes business sense for them and it won’t. Adobe is far ahead in almost every way. Their software is competing in the market of amateurs. And for an amateur, it should make more sense to pick up Gimp, inkspace. Affinity publisher is ok, but pros will have adobe and for anything less inkspace or figma free tier is good enough. Affinity has no market.
