I agree with you that these types of spending decisions should be thought through completely. All options should be carefully considered, and no supplier should be given a rubber stamp approval every time.
Agreed, neither proprietary nor Open Source (and to go on a tangent, neither minority-owned nor white-owned, etc.). However, I do believe that under objective circumstances, OSS and other free software models will win the majority of the time. It could be that is a fact, and that fact makes any fair competition bill look like an OSS-proponency bill because it will naturally advance OSS due to its generally better price/performance ratio.
