The problem is that "software that benefits you" is probably going to end up only benefiting direct dependencies while you would really want the entire dependency tree funded at the very least. Even that might be insufficient if you consider how much open source software benefits you indirectly, e.g. because some product you use that isn't software at all can be cheaper because that company has to pay less to get their website developed or because some data you need is available only because it can be hosted as an open API based on open source software.
