Nothing about Hacktivate is pay-to-win – you can solve every challenge without using a single hint, and even if someone does need hints there are a bunch given away for free. Even more, for people who want the game but don't want micro-transactions, there's a dedicated version of the game (https://apps.apple.com/gb/app/hacktivate-education-edition/i...) that is a one-time purchase with no in-app purchases at all.
