This is not the only possible outcome. Another approach would be not to offer software within the affected region. U.S. local news is often not available to European visitors now due to GDPR. Similarly, Canadian news outlets are not available on Facebook due to Bill C-18. If I was an indie game developer I would consider this approach and simply avoid selling within California.

Larger game studios would likely adjust as you say. However they too could adjust in such a way that they only offer subscriptions within California as that appears to exempt them from this rule. Many outcomes are possible beyond simply adjusting to the legislation in the way you are suggesting.
