For one job I also crossed some stuff out, founder was cool with it because he mostly got it from a template. Having actual paper is great for that. At a later job, they insisted on Docusign, which was basically I get an immutable image in a browser to 'electronically sign' with no modifications. It had a section that amounted to a non-compete agreement that I didn't like, but their lawyers didn't really answer me on whether such a thing could be enforced or not given that the company was headquartered in California even though I'd be working out of Washington. I took that as a sign that they probably wouldn't go Amazon on me, at least.
