Too many armchair engineers getting angry about other peoples bikes.
Just because something is heavier doesn’t mean you will notice the difference. I bet most folk would struggle to tell the difference between 1kg and 1.2kg. Even more so if you have 1.2kg in a tiny box and 1kg in a huge box.

Reminds me of the question put to a scientist and an engineer.
A woman/man (delete as appropriate) is standing in the middle of a room and you are at the doorway. If your first move takes you half way to them. Your second move takes you half as far again and your 3rd half again (continue) will you ever reach them?

Scientist: No, there will always be an infinitesimal distance between us.
Engineer: Close enough 😉
