Attention PGP Users: New Vulnerabilities Require You To Take Action Now (eff.org)
A group of European security researchers have released a warning about a set of vulnerabilities affecting users of PGP and S/MIME. From a report: EFF has been in communication with the research team, and can confirm that these vulnerabilities pose an immediate risk to those using these tools for email communication, including the potential exposure of the contents of past messages. The full details will be published in a paper on Tuesday at 07:00 AM UTC (3:00 AM Eastern, midnight Pacific).
In order to reduce the short-term risk, we and the researchers have agreed to warn the wider PGP user community in advance of its full publication. Our advice, which mirrors that of the researchers, is to immediately disable and/or uninstall tools that automatically decrypt PGP-encrypted email. Until the flaws described in the paper are more widely understood and fixed, users should arrange for the use of alternative end-to-end secure channels, such as Signal, and temporarily stop sending and especially reading PGP-encrypted email.

The key word was *automatically* – although it is not always clear in the press what you are supposed to do. So confusion will abound. No surprise there.
In the end, you can still use PGP, but you have to do more work to be safe. I think, if you understand how to use PGP to begin with, you can probably help yourself for now. If not, well ....
In your terms: keep your locks. But disable the remote locking feature (take the battery out) and don't use your app to lock your house - use your good old key you stored away in a box a long time ago. Yes, you will have to do actual work. And yes, someone can still break in - probably through the window. Or by kicking in the door ...
Do your own thing. And overdo it!
