100% this! Proton pass is convenient, but their email forwarding locks you into their ecosystem, and they limit your aliasing for your own custom domain. I started using it, and its nice, but I wish I knew about annonaddy before. I’d prefer making aliases using a custom domain so if i have to respond with a forwarded alias I can manage a way to reply from it, plus if I ever decide to leave proton, its not a road block. Sure you can usually change email addresses on sites, but may end up being a ton of work depending how many aliases you have, and how annoying the site makes it.
If your in the US you can tell them you’ll report them to the FTC and fcc as unsolicited spam text messages that have no means to opt out. They must provide a means to stop receiving text messages per can spam act. If they refuse you report them and then they face 50k in fines per message. You also get to have federal record at least that you didn’t want the text messages. You could also file a police report. The cops may roll their eyes, but just tell them you just want something on record that the former number owner waa a shady character and want to avoid any potential legal issues in the future for having their number and getting weird calls or texts.
