Tezos and zeppelinOS are very different things. zeppelinOS is building an operating system on top of the Ethereum Virtual Machine to provide secure infrastructure for the development of smart contract applications. A technology that is still being developed but used by thousands of developers, and maturing into it's next phase. Tezos is building a new blockchain with a different infrastructure altogether.

Millions of developers are working with Ethereum?

Thousands! Little typo over there. Hopefully soon they will be millions :-)
