Those three links don't support your argument here.

The Business Insider one is a paywalled rehash of this Reuters story https://www.reuters.com/technology/artificial-intelligence/m... - which was itself a report based on some data-driven PR by a startup, TollBit, who sell anti-scraping technology. Here's that report: https://tollbit.com/bots/24q4/

I downloaded a copy and found it actually says "OpenAI respects the signals provided by content owners via robots.txt allowing them to disallow any or all of its crawlers". I don't know where the idea that TollBit say OpenAI don't obey robots.txt comes from.

The second one is someone saying that their site which didn't use robots.txt was aggressively crawled.

The third one claims to prove OpenAI are ignoring robots.txt but shows request logs for user-agent ChatGPT-User which is NOT the same thing as GPTBot, as documented on https://platform.openai.com/docs/bots
