I wouldn't necessarily read too much into this.

I think most people's aversions to the concept of IPOs stems from the fact that it lies at the end of the not-too-uncommon lifecycle of VC-backed companies:

• Get VC investment
• Subsidize your product using said investment
• Grow like hell on account of handing out things at a too-low price
• Prepare for IPO by worsening the deal for customers to improve financials (also known as enshittification)
• Use IPO money to pay off VCs and leave both them and founders with a large chunk of money

Post-IPO the company has to abide by the regular rules of being a company, meaning that they never really re-capture what it was like when they had a large stack of free money to make all deals sweeter than the competition.

All this to say is that the damage is done once you raise VC capital. Raspberry Pi has raised one fairly small round, so there's potentially some damage done there, but it's way less than your average tech startup did throughout the years, so this doesn't necessarily have to mean that everything will go to hell now.
