I don't know that there are "camps" as such, but there are a few major issues that come up a lot. The "problem with lowsec" is basically that there is relatively little motivation to live there for many players. For PvE and mining, 0.0 is more lucrative and often safer, if you are part of a sov-holding alliance. You can't have sov in lowsec (ignoring the pseudo-sov of faction warfare) and the sec hits and gate guns make NBSI at least more difficult than it is in 0.0. The only times you see people try to strictly control lowsec systems are when they're running level 5 missions (or a few specific systems that are important for other reasons, like the Rancer pipe).
Meanwhile, if you try to carebear in lowsec, you're constantly at risk of being ganked. Lowsec complexes, missions, and belts, while more lucrative than hisec, are not that much more lucrative and therefore not nearly worth the risk for anyone serious about their isk.
The FW side of things is a little out of my experience, but in short it's another issue of the rewards not matching the risk.
The major opinion about lowsec being broken boils down to "so why should I bother." Solo players and small pirate groups can be found all over lowsec, mostly looking for PvP outside of the great blob fights of 0.0 or the aggravating restrictions and expenses of hisec warfare, and that works for them but it's not exactly broad appeal. CCP is actually trying to make something unique to lowsec in Incursion, as they've stated that the Revenant BPCs will only drop from lowsec incursions, not hisec or 0.0, but it remains to be seen whether that will change anything either in-game or in people's opinions.
As a disclaimer, these are not views I subscribe to, by and large. I see lowsec as useful, generally quiet areas of space where you can get in some fun PvP or solidly profitable exploration, but that's just me.
