There's more to this: Gov't acquisition through contracting has changed dramatically in the last few years where "Lowest cost, commercially available" isn't as straight forward as it used to be.
10 years ago, hell even 5 in some cases (GSA, ITES, etc.), the old rule of the cost-of-commodity (hardware/software) was still the primary consideration for awarding contracts - these days with the complexity of solutions (which have to be NIST 800-171 compliant (now including CMMC!!)) the PEO for the Gov't agency must look at the total solution - hardware, software, deployment, education, configuration, support, CUI Security, redeployment/recycling, etc. etc..
The real story isn't politics (/no cr, gasp!), it's that M$ is better at understanding PEO evaluations during contract awards than Amazon. I find it hilarious that Bezos is crying 'unfair' and launching legal action, when for years he was the pontiff of beating the other guy by a better business model, and fighting so many lawsuits himself.
