Your description of the experience only nodded in the same direction.
That's different for most services, e.g. if you ship a laptop to Minifree and they just flash it and send it back, they have to bill the taxes of your country. If they do any of it differently, they're doing a mistake.
There are other companies that can provide you with Libreboot, blob-free coreboot or other libre boot solutions on your Thinkpad if you're unhappy with their service (according to your experience that seems to be an appropriate response).
Minifree doesn't stand for the quality standard for the whole "libre community" as Albert Heijn (a supermarket chain) doesn't set the gold standards for the whole supermarket industry.
I won't have the time to set this up myself soon, so I went ahead and bought one. It's my rainy day laptop.
Leah is extremely unresponsive, when I ordered mine it took over 2 months for it to be shipped with no prior indication of this (it should've taken at most 3 weeks to arrive at my home), and any email response from Minifree took at least 3 weeks.
Oh, and Leah billed me UK taxes instead of Dutch taxes as per the EU webshop rules, so that was a lot of fun when I had to file my taxes.
The shittiest customer experience I've had in years.
