I was well aware of the licenses. I was optimizing for delivering value to my customers, not for the best way to give everything away should I go out of business. The world of licensing gets considerably more complicated once you decide to distribute it. There are plenty of things I'm free to use in a service capacity because I'm not distributing them. The issue of linking or derived works or license compatibility doesn't come into play for many licenses if you're not actually distributing software.
And that says nothing of the commercial products I licensed that I knew I wouldn't be able to sublicense. But, the name of the game was expediency. I liked the theme on WrapBootstrap. I paid ~$20 for it and got up and running in a weekend. Recreating that would have been considerably more effort at significantly more cost. I made a trade-off, as businesses need to do. It's technical debt, one I'm not obligated to pay and don't see the long-term value being worth it.
