No, this isn't a bad thing. It's a common misconception. Raspberry pi trading is going for an ipo. They've always been profit oriented. The raspberry pi foundation is still nonprofit, despite sharing some members.

Raspberry pi's business sector (aka Raspberry Pi Trading) has never been non-profit. That's who is going for an ipo.
Raspberry pics community sector (aka the Raspberry Pi Foundation) is the non-profit, and will remain as such.
