The world has changed, and moved on, from an owner in control "showing the flag" to help command respect for their property. (No disrespect meant, from your posts here I have confidence you were a quality owner and landlord ... as hopefully I am as well.)
The CA government decided to reign in greedy, underhanded landlords. Which in their view is all of them. Now, in many ways, the tenant is in control, not the owner. Such as if the owner decided they don't want to rent their property anymore. The tenant says "no, I am staying." The tenant's wishes prevail over the property owner, and the tenant has the power of the government to back them up. Maybe the owner is undergoing chemo treatments for cancer and cannot keep up with a rental, nor has the money to hire a manager. It doesn't matter-- the tenant rights have become superior to the property owner.
So a new mantra is in play. No more owners "showing the flag." Now it is the tenant "showing the statutes." That is progress?
