"Over the decades Yahoo! has contributed substantially to the greater good, publishing its own code as open source.
Arguably Yahoo!’s greatest legacy once it is a division of Verizon will be big data, after one of its engineers – Doug Cutting – wrote an open-source implementation of Google’s MapReduce that became Hadoop. What followed was an entire ecosystem of startups and projects crunching data at scale – Cloudera, Hortonworks, MapR to name three in a market some calculate will be worth $50bn by 2020."
Generally when you disclose something (like the fact that you run the open source process at Yahoo) that's a disclosure, rather a disclaimer.
A disclaimer might be considered the opposite "I don't run the open source process at Yahoo, but...", or, more commonly, "IANAL".
Very optimistic calculation...
Hopefully Verizon's open source legacy will become even bigger and make it easier for these kinds of innovations to happen.
We've had some success a few cities over in Verizon Labs...
