You argue that Facebook's revenue for 2018 was $55.8 billion, which means that the $500 million fine represents only 0.9% of the company's annual revenue. That's a valid point, but we need to consider the broader context. Facebook has been under fire for its data practices for several years now, and this fine is a signal that the company needs to change its ways.

Furthermore, you point out that Facebook's stock price increased by 2.5% after the FTC announced the fine. While this may suggest that investors don't view the fine as a significant penalty, it's also worth noting that the stock price has fluctuated significantly ever since.

I think it's important to recognize that Facebook has made efforts to improve its data practices in recent years. For example, the company has created a new position, the Chief Privacy Officer, to oversee privacy and data protection. Additionally, Facebook has implemented new tools to help users manage their data, such as the "Off-Facebook Activity" tool, which allows users to see and control the data that Facebook collects about them from other sources.

Can things be improved? Sure. And controls need to work properly, always. Unlike with TikTok these days...
