I earn more than $5 or $6 with these programs and I am sure most people who have been giving these programs exposure to good traffic do so. Not every program performs for every person or site, so you need to drop what doesn’t and replace it until you find what works for you. That is part of the growth process.
My stats update and when there is a problem, like with fortune, I am aware of it and watching developments. Whether you wait and watch like I am doing now, or whether you want to pull right away depends on you and your bottomline. By all means don’t waste your traffic on a place that is not working for you.
If there had been an actual finalized merger, where money changed hands and ownership changed, in January, I am quite positive I would know about it.
So I am not concerned with your “ifs”. They are speculation and highly unlikely.
