I can't speak for the original poster but one thing that I noticed is that from time to time it happens to me that despite not having a tight deadline I tend to not go all the way in avoiding tech debt.
One example would be that I had a problem in one of the microservices with a version of a docker image that wouldn't run on an M1 mac. I fixed it in that repo but didn't do the same changes to other services with the same issue. Changing the other services would have taken me less than half an hour. This is the kind of laziness that the article and qup are referring to I believe.
