All those online services, even the AI ones, need servers and bandwidth and paid people to maintain them. They need sources of income and the only reliable one known to man (today) is ads. If you have a different idea, please do explain, but before you say "monthly contributions" think twice about the reality of it and maybe also count for how many services you personally pay. Of course one could say "why do I need online services at all" but that's not a future I care about.
