"My boss suggested Free AVG" ... "We cannot allow ... to leave our business"
So, you admit that you have been using the "free" version of AVG in your business.
Did you ever consider that it was, at least in part, arsewipes like you/your company, illegally using the "free" version which is specifically NOT licensed for "commercial" use, that may have contributed to the lower revenues at AVG that presumably contributed to AVG's decision to further monetize the free version of the software?
"I have just been asked by my boss whether we can opt out of the metadata sharing".
Sure - pay for the commercially licensed version, as you should have been from day one...
