loftar did the client that way because he doesn't want to bother more about atm - and he wouldn't give the client source if he wouldn't want customs ... as he knows about the restrictions in his client ...
there was a time when only few had access to custom clients ... thanks to all who stepped in (Pacho, Gilbertus, marvi, Ender ...) we're all on par now ...
besides the technical and buerocratic efforts it would take to exclude custom clients there's always a way to bypass that ... which brings us back to where only the choosen few have access ...
... and this had been discussed over and over and over ... resulting in having a wanted varity in custom clients and loftars ... the choice is ours
to get back on topic:
i recommend to check more than HnH and clients when it comes to instabilities ... progs and services running, faulty drivers ... or even dust in the fans ...
