Voi nu aveți cuvînt Românesc pentru "hobby" - este foarte desgustător să împrumuți cuvinte care nu sunt ale noastre și să le Romanizezi
If you think so, then you'd be appalled by how natives actually speak, romglish is extremely common. Also, this is how languages evolve, a lot of "Romanian" words were taken at some point from other languages (mainly French).
Seeing how this word is both in DEX and DOOM, it's pretty much a "cuvânt Românesc". IMO, it's a lost battle to try to convince people to adapt its spelling to "hobi".
