can big companies like amazon, google, facebook, or apple kill ethereum?
Possible Reasons:
-much more money
-more business partners
-more employees
All of them had a different market and users, and I don't think these companies can beat or kill Ethereum, what can kill Ethereum is the community that supports, but people are unanimous in supporting Ethereum just like they do on Bitcoin, as long as people are into Cryptocurrency Ethreum is unlikely to die.
