Curious do you just stick with web apps or just don't do any sort of business that requires it? I was thinking about a career shift into apps or web apps, leaning towards web actually because I do have a little bit of "full stack" experience on simple web applications/databases in the embedded sphere.
Yes I now focus on business ideas that cannot be blocked/banned/rejected ... Since 2011 I had 4 startups that where killed by either google, apple, Facebook and YouTube.
In 2016 I decided to avoid them as much as possible and never rely on third parties, ... Yes this is discarding a lot of good business ideas ... But your business then cannot be killed by a third party at any time
