Why did Ahrefs raise their prices big time?

I was paying $79 a month for services Ahrefs now wants $249 for. Other than the fact Semrush charges that amount does anyone know why Ahrefs did that? I know they wanted to move their servers to the US so they would read things the same way as google. Does anyone have a recommendation for a service that does what Ahrefs did for a lesser price? Sure a lot of the stuff can be figured out other ways, but Ahrefs is all in one place and seems more reliable than the competitors.
