That doesn't look at all like a language barrier problem. That looks like Lennart understood perfectly well, that usage of the pool is conditional on registering a vendor pool and that he has perfectly sound reasons not wanting a systemd vendor pool. And note, that the main Maintener of the NTP pool agreed with his reasoning. I also somewhat agree with Lennart, that the reasons Google give don't really apply. However, I also agree, that they shouldn't be used nevertheless :) Luckily, as I understand it, there seems to be somewhat of a concensus to not put a default and instead have fail the build if nothing was ./configure'd.
