As explained in this Reddit post (https://www.reddit.com/r/OpenBazaar/comments/acz3go/why_dont_you_accept_monero/), the OpenBazaar team is open to the idea (thanks to multisig) but has not enough resources to implement Monero on their platform.

The OpenBazaar integration could be a good idea for fungibility and maybe we could use the funding system to develop it.

Excuse me in advance for mistakes, wrong idea, something more. Regards.
