Tried to install FP from Adobe.com the installer wants you to sign up for stock photos at $29.99 per month after the first free month. I just want a clean version of FP to install on Mac OS Sierra. What's the problem with Adobe?

Thanks for your valuable feedback.

For better or worse, the bundled offers and product promotions pay the bills.  While Flash Player is free, Adobe is a for-profit corporation.  In order for a product to exist, it has to make money. 

While I'd love to live in a post-scarcity Start Trek style meritocracy, that day seems very remote.  In the meantime, we don't have the luxury of just spending money without generating income.  Maintaining and distributing Flash Player is a tremendously complex and expensive undertaking.

At the end of the day, we pay business experts to research, identify and implement the most effective business strategy.  The experience you see reflects the approach that yields the best results.  It’s also the case that those bundled offers keep me employed, and it would be disingenuous to just blame it on the business people.  The decisions about how and where things get monetized happen way above the pay-grade of anyone responding here, but they're made with the understanding that not everyone can be pleased.

The truth is that a sufficient number of people find enough value in the bundled offers that they ultimately spend money with those sponsors, who in turn see real value in sponsoring the availability of the product(s) that you're using for free, which in turn keeps us supplied with engineers, servers, bandwidth and coffee.  It’s an imperfect solution for an imperfect world.

That said, you actually *do* have a few options at your disposal in terms of avoiding a monetized installation experience:

1.) Enable automatic updates. 

You do not get prompted for background updates.  We actually forego the revenue opportunity to ensure that you're always updated with the latest security patches.

2.) Use Google Chrome or Internet Explorer/Edge on Windows 8 and higher

These browser partners contribute directly to the Flash ecosystem in multiple ways, and distribute Flash Player as built-in components of their browsers.  There's nothing separate to download or install, and Flash Player is automatically kept updated via either the Chrome updater or Windows Update, respectively.

3.) Uninstall Flash Player

While probably not the optimal answer, you can always opt-out of participating in the ecosystem.
