2things.
1, Spam that contains my Whois data is very much more concerning, especially if it looks like a legitimate service I may already be using.
2, if a company collects my Whois data, and justifies monetising it to me or you, especially under the guise of ‘its for my/your security’, and I am not financially compensated for it, or I am unaware of it, or unable to change the terms and conditions of access/usage of it, then I consider it stolen.
