There is no arrest warrant for Google, Facebook or ad network employees either despite them violating the GDPR on a daily basis and very large scale. Granted, the GDPR doesn't say anything about arresting offenders, but the companies should at least be investigated and fined, which isn't happening either. The GDPR is a joke.
As long as they process openly available data I do not see a difference from searching your name on the internet in terms of the gdpr. They also responded to the request (maybe not fast enough) . Deletion would be a difficult thing maybe to be fully compliant to eu regulations .if its ethical is another story...
PII may only be processed if you have explicitly consent for the exact purpose you want to use it for.
There is no "open" personal data you may just use for anything.
