I don't want to require an up-to-date computing device to visit my website. I have HTTPS (with modern ciphers and protocols) for my website, but I also serve it as HTTP. I really do appreciate the advantages of HTTPS, but I have issue with the time-bombed nature of the technology: website certificates, root certificates, and ciphers that become less secure. I do not like that old devices can essentially no longer use the web due to HTTPS.
