If you were to go to my website (
www.diamantstudios.ca) with Chrome, it will probably won't let you in. Reason: the SSL certificate is expired. It's been so since AD 2017. I don't pay for SSLs: no point in it for a site that basically makes me no money and it's merely informative: I'm not selling anything there other than my services and for that people would need to contact me directly. The only personal info that is 'collected' is whatever is put in the Contact form if you chose to use it and it's nothing I could use to empty your bank account or steal your identity.
Could I use a 'free' SSL certificate? Sure, and I might do so in the near future. Point is, many 'free' certificates are just a means to bend website owners over. A very popular 'free' SSL cert issuer turned out to be a front for the Chinese to steal info.
Now, Firefox lets you add security exceptions to those sites and browse on: that's what I always do. Chrome won't let you do that, though: Chrome is Google, and Google makes money off search ranks and categorisations and other stuff: it's in THEIR interest to try to force every website owner to buy certificates because that fuels the Internet economy from which they profit immensely. It has nothing to do with your protection or security: they couldn't care less if you were hacked, botted, or had your data held for ransom. It's just control on their part with the excuse of 'protecting' you. Have we seen that elsewhere? Of course: many are now following that business model.
