I think its just pettiness really.......
The acid fever represses are a blessing to anyone sick of paying £50 a time on ebay over the last few years. I sold off all my acid fever originals a few years back for up to £70 each - crazy money!! I might get the represses just to rub it in.
Its not like acid fever hadnt repressed a couple themselves anyway - http://www.discogs.com/label/Acid+Fever+Repress
I dont see the problem - unless you have been shelling out silly money for the originals - even then there probably still worth what youve payed to a collector who wants original sleeves / cat numbers etc.
fair play really - could do with more of this sort of thing IMO
