I would not trust a company with my email that does not even publish its full name and/or address on their website. It's not even clear under which jurisdiction they fall. This is an absolute non-starter for me. I will stay with Migadu who are very clear about these details.
Checking with https://www.amiunique.org/ resulted in a unique fingerprint for me. The "Canvas" and "Media devices" attributes are unique on their own. I had not expected this.
I don't understand the apologetic tone of this post. At least where I live this behaviour is illegal. These cops must lose their jobs and go to jail. Their job is to protect people, not injure them. F*k*g b*t**s.
