I don’t know for sure (i’m not Google ^^) but that is what I am reading nearly every day at reddit. One dev gets banned, then few months later he uses an other play dev account and this one gets banned as well.
In general the company is only at risk if the dev will use their play store account. Unfortunately this is more probable in small companies / startups than in big companies. Meaning this extreme change hits more small fishes as big ones :(
