Glad you enjoyed it :)

There are plenty cool talks from the chaos communication congress event, the hacker event. I put the link at the end of my post.

For example this one is crazy :

A 595€ wheelchair remote that sends a handful of Bluetooth commands. A 99.99€ app feature that does exactly what the 595€ hardware does. A speed upgrade from 6 to 8.5 km/h locked behind a 99.99€ paywall - because apparently catching the bus is a premium feature.

Welcome to the wonderful world of DRM in assistive devices, where already expensive basic mobility costs extra and comes with in-app purchases! And because hackers gonna hack, this just could not be left alone.
