The Logic Behind Bloatware

[Fredledingue]

Please somebody explain me why some softwares are ten times bigger than other ones for similar activities.

Often commercial softwares are 10x bigger than their freeware alternatives. While commercialwares usualy do more than their free concurents, it doesn't justify such disproportionate difference in the file size.

I don't understand that since it seems to me that it takes more time to write 20 Mb than 2.

Or is it that developers for commercial companies must work fast and copy-paste packs of codes toghether, no matter how manyfold redundant they are?

While freewares are written within the state of the art of efficient programming?

from my experience, freeware programs are programmed to do one or a few things, which keeps it simple, small, fast and easily updated

as for commercial programs, either they try to do to much inside a program (chances are, that in ms office, a majority of the features wont be used) or they evolve above their original purpose
