A big problem is that you don't get a choice. It would be one thing if you could just take or leave the patented technique and benefit or not from it. If you could then the holder of the patent monopoly could only extract the marginal value of the patent. Unfortunately, patent holders frequently act to create hold up to extract far more than their share and prevent users of technology from being able to choose to not do business with them (at least without severe collateral damage).

You might find this now 11 year old writeup informative:

But even that assumes that there is some actual valid patent, in this case no patents are identified on the website, they're simply "calling" for patents.
