There's a big difference between saying something with a positive spin (vanity metrics, unfounded optimism, etc.) and photoshopping a fake picture of yourself with celebrities.
Most of your examples of lying are just about interpreting things differently. To an entrepreneur, their company is heading in the right direction because the signups are consistently going up. Sure, they haven't figured out how to keep those people engaged yet, but building a successful company takes time. There's not a blurry gray area between focusing on the positives and completely making something up that's provably false.
Yes, there are plenty of liars out there, but I don't think most of the behavior you're describing in your post fits that description.
