This is the real way to hurt a company. Once an open source version exists, even if it is not as good as the commercial offering, they will have trouble convincing people to pay for what they are selling.
Of course, they should be compensated for their work, but if you can build it yourself then the cost to a company does not need to be much higher than the costs of parts and labor for someone else to do it for you.
One of the things I want to do is build decent applications and release them for free so people can get the same functionality of their paid apps but not need to pay anything.
Military tech companies will be perfectly fine. They typically have 10+ year contracts, and military equipment has a huge price margin in exchange for being reliable and field-serviceable, and the main disadvantage of DIY radar is reliability (unless you also recruit the guy who built it into the army).
It will probably impact civilian market more, where the same companies will try to sell you an unnecessarily hardened machined aluminium box full of cheap Chinese electronics, camo painted for an additional ten thousand bucks.
Their next commercial offering might just be cheaper.
