It's not that people go "oh man, feet solvers are all evil people and I hate them", it's just that feetsolving is an annoying event to deal with.
From the organizational/practice standpoint feetsolving is annoying because many people consider it unsanitary and thus it is hard to get judges/scramblers to help out. For instance people won't want to touch a cube or stackmat that has been used for feetsolving or will want to wash their hands afterwards. It's also a relatively long event to hold because even people who are bad at it (like 3+ minutes, and yes that IS bad if the WR is 47.xx avg) want the rare chance to compete. In the US it is almost never held (only 3 competitions have ever had it) and even in Europe it is not all that common, and I think the reason is just that it is somewhat impractical and annoying to deal with.
Derrick: right, but 3x3 with feet IS a side event. You usually don't expect more than one round of side events, no matter how much you care about it, and even the one round is dependent on timing issues. It's not that side events are dumb, but rather that main events (such as... 2x2) are more important and popular, and in that sense much more deserving of having extra rounds (or rounds at all, if time is short). I mean, I've practiced 7x7 a lot and only ever had one attempt at it, but I understand that it's a side event so I'm not going to go around complaining that organizers aren't giving me two rounds everywhere I go.
