> you can't broadcast facts into the public and expect people not to recall them
That's a straw man, that is not the issue here. LinkedIn is not recalling the data, they asked to stop HiQ from scraping and collating their data and using it for their own business.
This is already in the EULA, so what HiQ is doing may already be breaking the law.
