I think this will be a pretty impactful moment for OpenAI. I mainly use ChatGPT and use the free plan, so I expect to start seeing these ads. If they become too annoying, I have no problem moving to Claude/Gemini. Sure I have stuck to ChatGPT, but I wouldn't say that I am too sticky of a customer. I personally think they are doing it sooner than they should (which probably points to internal financial struggles as they seek to go public) and will erode their active users. There is simply too many easy alternatives. It's not like Netflix where if you are annoyed with ads and don't want to pay for a higher tier, you're more stuck. Yes there are other streaming services, but you can't get the same content.
you really believe that gemini by google will not run ads?
