Despite the submission title, I don't think I would call this proposal a way to force companies to pay for free software. They could choose not to pay if they don't want to use the software. If they've already downloaded the software, then they wouldn't need to pay unless they want to download it again, but they are free to make as many copies as they want so re-downloading is mostly going to be a matter of convenience I think.
I believe free software is better than proprietary software, so I think it's good to better incentivize the production and maintenance of free software.
