When the CCPA launched in 2018 companies had to comply when a consumer requested a Data Subject Access Request (DSAR). Because the consumer had to request a DSAR not all companies felt this compliance pain acutely (e.g. it was mostly big companies with A LOT of users that got more DSARs, so they adopted workflows and tools to alleviate the pain).

The Delete Act has more teeth. Independent compliance audits begin in 2028 with penalties of $200 per day for failing to register or for each consumer deletion request that is not honored. GDPR spurred organizations to compliance, partly because of the steep penalty (up to €20 million or 4% of revenue, whichever is higher), maybe The Delete Act (and its much smaller penalty) will also spark organizations to comply.
