If only Microsoft had run with the idea of package management and trusted repos that has existed in open source for decades without restrictions that inspire people NOT to use it.  Example to release a debian repo to share your software with your users you have the option to handle hosting&#x2F;payment if any yourself and keep 100% of the revenue not 70%.<p>Their position in the market is such that had they started pushing this around the time apt-get started to be a thing they would have had near 100% adoption and users would be used to installing everything that way and would be naturally suspicious of manual installation.<p>Bad actors could end up on a blacklist that users would opt to enable.  You would even have multiple black list sources from people like antivirus vendors etc.
