Neither Gonzo nor BONES is young at this point. Gonzo is roughly 15 years old, BONES roughly ten. Both studios were founded by industry veterans who were ready to go their own way (of GAINAX and Sunrise, respectively).
Personally I feel Gonzo deserves no support whatsoever, because the studio was founded for abominable reasons. The founders of Gonzo left GAINAX explicitly because they felt GAINAX was missing out on commercial opportunities by refusing to produce more shows per season at lower levels of quality.
Gonzo occasionally produces a classy series every now and then, but if you look at the bulk of its production credits it's trashy, poorly-made series of the sort that helped ignite the now-embarrassing boom for anime that run on pure crass fanservice.
I feel BONES does deserve fan support, but international licensing brings pride and prestige to a studio. BONES's success with officially licensed versions of its products in the West has helped keep the studio alive. If you support officially licensed Fullmetal Alchemist or other BONES projects in the US, you are supporting BONES just as much as if you buy Japanese-made goods.
um a studio that is younger than i am is not old is Tatsunoko or toei or Sunrise so bones and Gonzo are young in my eyes no more of the money goes in Funi or the license holders if you buy the stuff in the us
