Of all the parts invloved in setting up a web server, is adding a letsencrypt a significant further barrier? In what situation would a non-tech-savvy user ever be doing that in the first place?
Hint: not all web servers run inside Facebook or Google or Amazon data centers. Some of them run inside individual devices, which will now end up in the landfill once their certificates expire. Many such devices were, and are, just fine running plain old HTTP, but now they're all going to be subject to service life limits imposed by a third-party authority.
This is not how this was supposed to work. This is not how any of this was supposed to work. But it's hard to voice any objections over the proverbial thunderous applause.
