My current company doesn't prohibit using VS, although there's something in the manual that basically says "pay close attention if using VS".
At my previous airline, 90% of the pilots used VS in the climb. I never liked it. The AP had a pitch hold mode which I'd prefer to use. Never a dull moment though, as I had a CA criticise my use of pitch hold mode, as I was "more likely to stall at altitude in PITCH mode than VS mode"
