It means that Stripe is not ditching cryptocurrency - instead they are picking a more efficient coin.
A bit more on it in the following article:

“OmiseGO is an ambitious and clever proposal; more broadly, Ethereum continues to spawn many high-potential projects. We may add support for Stellar (to which we provided seed funding) if substantive use continues to grow.”
The blog post mentioned a few other altcoins such as Litecoin, Bitcoin Cash, and ‘other Bitcoin variants’.
It looks like they'll enable several cryptocurrencies and let users choose which one they want to use.
