There's a difference between putting information easily online for your customers or even people in general (eg as a hobby), and working in concert with scraping for greater visibility via search, and giving that work away, or at a cost, to companies who at best don't care and possibly may be competition, see themselves as replacing you or otherwise adversarial.

The line is "I technically and able to do this" and "I am engaging with a system in good faith".

Public parks are just there and I can technically drive up and dump rubbish there and if they didn't want me to they should have installed a gate and sold tickets.

Many scrapers these days are sort of equivalent in that analogy to people starting entire fleets of waste disposal vehicles that all drive to parks to unload, putting strain on park operations and making the parks a less tenable service in general.
