Businesses are inherently lazy. Business shrewdness and laziness are literally the same thing; businesses always take the easiest path to the greatest profit. "Lazy" just means "unwilling to expend energy".

Let's say Dow Chemical wants to start dumping chemical by-products into the Mississippi River. Thankfully, we have the EPA and strict laws which make this impossible. The only other force which would stop them from doing this is consumer outrage, which only works in some situations and even then tends to be very fleeting.

Now, let's say Slack wants to build their app in Electron. By doing so, they are collectively forcing their 8M users to burn more CPU cycles and purchase machines with larger memory footprints, all of which literally waste resources and cause pollution. Not to the same degree as the previous example, but the comparison is very valid.
