Somewhat related - who came up with the idea of stuffing all that domain verification tokens directly into TXT records for the domain?

Just querying the TXT record of a domain might give you an idea what products a company is using…

That leaves UCEPROTECTL3

Is anyone still using them?

I see a lot of spam coming from sendgrid, so I wonder how long they can continue operating that way until they get blocked completely by one of the larger mailbox providers.

see https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p3471r2.html#enabling-hardening

Much like a freestanding implementation, the way to request a hardened implementation is left for the implementation to define. For example, similarly to -ffreestanding, we expect that most toolchains would provide a compiler flag like -fhardened, but other alternatives like a -D_LIBCPP_HARDENING_MODE=<mode> macro would also be conforming.

I wonder if it would be possible to build such a tool on top of tree-sitter (although not sure tree-sitter’s C++ grammar can handle modules yet)

“they put ads in the terminal” isn’t really accurate.

Their “ubuntu-advantage-tools” adds information to one of their other products to the output of apt. You can easily get rid of that by uninstalling/replacing “ubuntu-advantage-tools”. It’s definitely not like they are selling ad space in your terminal to third parties.

I am using a single package from Mint, the rest is Ubuntu 23.04. Mint would otherwise be based on Ubuntu 22.04?
