Subject Re: opscentrer is spying

I use Cassandra, but I don't use OpsCenter.

Seems like it would be in everyone's best interest to clearly define what
data OpsCenter collects today, what OpsCenter won't collect and a promise
to users none of the data will be used without first getting a customer's

I can understand the desire to collect general statistics, since it helps
developers get a sense of how cassandra is used in production. I'm guessing
these types of security issues can be easily addressed by improving EULA,
documentation and communication.

my bias 2 cents as a user.
