Sure, however think about that: $7m may sound like a lot to us, but it's just 0.1% of this hedge fund. Even if they wanted to focus 99.9% on shitcoins, they could absolutely do that without pressuring Passport into any weird direction. 
Yeah it's not a lot when you look how much money they have, but they won't throw away money just like that.Foundation Devices also raised $2 Million last year, so you do need money flow to keep running things for any business.
Let's compare that with Ledger who collected $380 million from last year series C fundraising, that is really a big difference.
I personally wouldn't mind if they allow adding few other shitcoins that are privacy based, but I know the road is going down the hill when that happens.
PS
It would be interesting to collect foundrising information for all hardware wallets, but this would be tricky thing to do,
You would need to find who exactly invested money, how much they invested, and find som reliable documentation or links for that.
Why would they switch to MCU RNG instead of using the Avalanche noise circuit?
