In this case landlords could just pay some money to fake tenants to make their rentals appear occupied (at a ridiculously low price). Rental prices could even rise because of free rentals number reduction and necessity to cover additional expenses.
My experience is the opposite. A colleague who uses SourceTree and git console (for use cases not covered by SourceTree) asked me a few times to fix his branches when something went wrong (after using git console). I easily fixed it using SmartGit (paid software).
