It sounds a lot more like you don't fully understand what the causes behind these things are and you're ready to arrogantly blame it on developers who dare use javascript without microoptimizing everything.
Your email client has a 300MB memory footprint most likely because of its dependencies and the appropriate amount of work invested into it. If it's a commercial product, the company probably doesn't care enough to spend decades optimizing every single layer of the stack down to the compiled assembly just to sell you something for twenty bucks. If it's an open source product, the devs behind it definitely don't have time to do that but OTOH you're welcome to apply your superior knowledge and show everyone how it's done.
