In the very 90s I worked for a few different tech or engineering / services companies and at more than one I learned that the early days of the company were full of similar stories.
I think it had more to do with the nature of an early tech startup combined people with a white collar office setting and sometimes long hours that allowed for social mixing, goofing off, encounters the left people saying 'check the sofa for stains', etc. Add in some corporate success in lines of business that weren't 'mature' to the point of being cut and dry and it was easy to blur the lines, especially with younger people who were not married / didn't have families (though that didn't stop some).
