You know it's easy for companies to push people around, when they have grown into the fat cats.... They must just not forget who are the hand feeding them.
There are alternatives for every service rendered on the internet. OpenBazaar is still small, but once Bitcoin goes mainstream it would take a significant market share away from eBay, if they continue with this
type of bullying.
We have seen this lately with
VISA / MasterCard vs BackPage and also
Reddit vs VoAt... Companies are so focussed on making money, that they forget about the needs of the people that feed them.
These are the type of services, that would feel disruption the most, because they alienated Bitcoin customers.
