To say that all these bands were British DIY (or that Kleenex/Liliput was Swiss DIY even) is not factual. Several of these bands had other people's labels putting them out, and while most of those may have been DIY labels, some such as Cherry Red and Rough Trade were enmeshed in a distribution network that got records dispersed to stores all over the world, thus enabling certain of these bands to sell units into the tens of thousands. This is not at all like the method of production of a record by the Desperate Bicycles, the agreed-upon godfatherly band of the British DIY scene.
A truer respresentation of punk-informed DIY music that wasn't necessarily "punk" can be heard in the incredible "Messthetics" series on
Hyped2Death.
