By "freeride" they probably mean it lacks the ability to deal with high-speed impacts, which is a common issue with low-end forks. It's not "freeride", it's just low-end. This is like the old marzocchi Z1 "dropoff" and Boxxer Race models that lacked any kind of high-speed circuit. Low speed damping is fairly easy to put in a fork, as it's just an orifice and the fork doesn't have to move all that much oil all that fast, but if it's a high speed impact, you somehow have to very quickly increase the size of the orofice, which takes much more advanced circuits. Of course, it's borderline stupid to think that freeriders aren't going to ride the same kind of terrain as downhillers, the only difference being they get themselves to the top and ride trails that aren't as much downhill all the time. There's going to be plenty of high speed impacts, meaning this fork is going to be pretty crappy much of the time if it lacks high-speed damping, but by "freeride" they mean that it'll "take a drop" or a big jump, thanks to the low speed damping and coil spring + air volume.
They used shimmed damper setups from back in the late 90s with the first generation of rockshox and marzocchi forks. They moved away from this for some time, but eventually came back to it and we have some very good performing stuff now, we are even starting to see a little trickle down to some lower products like the marzocchi CR stuff that isn't terrible, as it actually has a shimmed damper in it similar to the higher end stuff. Many products still exist that don't just lack the adjustments of the higher end stuff, they lack the dampers that allow you to ride through varied terrain without the fork feeling like a jackhammer or making you lose control. Thankfully rear shocks have been pretty consistent through the years, but front forks have been all over the -bleeping- place.
Forks that "do not perform" at certain speeds are a pet peeve of mine. Jr T, Z1 Dropoff, Wedge, Z3, Z4, Z5, Monster T2, Boxxer Race, Judy T2, etc. Work ok in the showroom or in the parking lot at parking-lot speeds, but as soon as you try to do something like actually ride a DH trail, they bite you in the a$$ and you are fighting the bike the whole way down the mountain, which is not fun.
