A lot of the actors involved tend to be hustle culture types who think they are OWED your data, regardless of the ethics, laws, being a good citizen, whatever. They will blatantly disregard terms of service and hide behind massive setups such as these to circumvent protection etc.
And the problem is, if you run any sort of business or service that is data oriented, there will be thousands of people that will do this, which will cause you to devote enormous amounts of time, effort, money, and infrastructure just to mitigate the issues involved with data scraping. That's before you are even addressing whether or not these people are "stealing" your data. People who feel they are entitled to the crux of your business aren't bothered by being nice in the way they take it - they'll launch services that will cripple infrastructure.
Whenever I deal with a scraping process that decides it wants my entire business, and it wants all of it RIGHT NOW, or in 5 minutes, I want to find the person and sit them down in a room and tell them "hey, develop your own ideas and business. Ok? Thanks"
And if you think this was a problem before, it's exponentially worse over the past few months with every Tom, Susan, and Harry deciding they must have all your data to train their new LLM AI model. By the thousands.
