How FB Ads retargeting may collapse with Apple/Safari's cookie lifespan change to 7 days

Came across this article recently that I thought would be important for indie hackers as this will change a lot of marketing and user acquisition strategies

TLDR from the author:

What will happen:
🍪Conversions are not attributed to ad clicks when these happened +7 days prior.
🍪Your retargeting audiences will last for maximum 7 days, then they're gone.
🍪 Exclusion audiences of past Purchasers will only last for 7 days, after that your ads will start showing again to people who just purchased from you.
🍪Lookalike seed audiences are super small (filled with just 7 days of users), so the resulting lookalikes will be of low quality.

Impact:
🍪 The number of available conversion events will be limited.
🍪 If you're running ads for app installs, you're basically screwed.
🍪 Conversion windows will be limited to just 7-day click
🍪 The size of your website custom audiences will decrease.

What you can do:
💡 Start collecting email addresses from your visitors as a major part of your strategy
💡 Sharpen your customer persona / avatar.
💡 Verify your domain with Facebook
