> The Linux way of installing the apps is merely a convenient tradition. You can still put the app files anywhere and run. It will put its configuration files wherever the developer wanted them (conventionally the app dir is meant to be immutable and the files are meant to be stored under the user's home dir though). In fact many apps (incl. Chrome and PyCharm actually are installed the Windows way under /opt which is an equivalent to C:\Program Files\).

I don't think he was disputing the technical possibility of it. It doesn't help him from a user perspective though to know that this is merely a convention and not a technical limitation.
