"In the coming weeks, we’re also planning to start testing ads in the U.S. for the free and Go tiers, so more people can benefit from our tools with fewer usage limits or without having to pay."
Yeah, the predictions of doom are so wildly misplaced. There's even a sibling comment on this thread saying, "When Google introduced ads [note: in 2000], it made the product objectively worse." Sure, and did Google die as a result? Or did it subsequently go from a startup with modest revenue in a company with a multi-trillion dollar market cap and $100 billion in quarterly revenue?
Threads introduced ads and almost no-one cared. This will be the exact same result.
If you don't want the ads, then pay $8 for ChatGPT Go.
