According to Motherboard, Apple, along with lobbyists from tech trade organization CompTIA, reportedly told legislators that owners trying to fix their own iPhones could hurt themselves in the process if they damaged the lithium-ion battery.
According to The Verge, California Assembly member Susan Talamantes Eggman, who introduced the bill both in March 2018 and again in March 2019 said that Apple had also "sown enough doubt with vague and unbacked claims of privacy and security concerns" resulting in the bill's co-sponsor pulling it at the last minute.

The bottom line is that Apple doesn't want people fixing their devices. The reason why is probably a combination of:
