Clumsily putting cryptocurrency features in their app will look bad, I agree. Hopefully it won't be "jammed in" and in-your-face: just another feature among many (besides, doesn't it make sense to manage your keys for things, including cryptocurrencies or any other application, on something called keybase?)
But I think for the average platform, taking money from cryptocurrency foundations is a lot better than taking VC money. This was seen recently with the Matrix funding by Status token. Cryptocurrency goals usually need the platform to be open: just having a big integration with your token or cryptocurrency system can be a massive boost to your ecosystem. On the other hand, VC goals eventually require the platform to be closed off to milk all their users with actual "monetization plays" like Slack has recently done.
