So this might provide a credible support foundation (as opposed to miners tapping other revenue streams like milking the userbase for intelligence data.)
If there is revenue stream, it will be tapped, regardless of what other sources of revenue there might be. Those who don't tap it will be uncompetitive. It doesn't really matter if the baseline is zero or nonzero.
That is not true in a lot of cases, and this case in particular. This because the intelligence only has value if the antagonist (in my opinion of things) has a certain quite large global footprint. As an example, it probably does not have much value to Theymos what IP I come in on, and it may well be a negative to him so he may actually seek to avoid keeping that data at all. (On the other hand, he may be selling it for all I know.)
I would anticipate certain sidechains emphasizing privacy and taking great pains to avoid data leaks in their operations. This may limit the nature of the mining efforts from whom they will accept support.
