I think the case could be made that purism and similar companies are not playing on a level playing field.

Think for example about regulations regarding cellphone number portability. They supported porting a phone number to switch providers fostered competition and lowered cellphone rates. (not perfect, but much better than before)

Without that regulation new or smaller companies - even those providing better service or lower rates - could not get customers because of simple shenanigans.

(Is Purism really even shipping? I ordered in 2017 and haven't gotten mine)
