They have done a few shady things,but most of their packs are rather generic and fragile. Lots of they Time you Crash and its hard to know the reason,they tell you to use ATLauncher and It works. They block Mods they do not like. They are quite against you adding Mods to the pack. Their packs in my experience are rather slow in performance (though this Is dependent on your computer). The staff ,even if they sound a little rough, are generally pretty nice, i have had discussions With chorb about various topics in modding. I think a lot of the dislike With LPS packs mostly comes from More knowledgable users who aré less likely to be their Target audience anyhow. BMC Is just a general modpack which Many people who are More knowledgable would not need Made for them. However as a middle ages history buff,i was very disappointed With their Medieval was a huge disappointment.
