Copy-left licenses can work better for companies than non-copy-left licenses, if those companies are actually interested in improving the thing or creating the thing. They can release as GPL or AGPL and then profit from others contributing. If they released as MIT or other non-copy-left license, any competitor can use and modify without contributing back, which is the actual scenario any company should be afraid of. Copy-left actually helps companies that are not simply leeching.
