Philips Hue will force users to upload their data to Hue cloud - Home Assistant

I was always skeptical of Philips Hue because they seemed shy about using local only or even the fact that they're just zigbee bulbs in their marketing. I ended up going with Sengled zigbee bulbs for myself, but I've always heard that Hue bulbs have the best brightness consistency and color. Also been noticing lately that the smart bulb market has been flooded with WiFi and Bluetooth bulbs, and there really isn't a lot of choice left in the zigbee/local only market. Hopefully this change by Philips doesn't lead to them dropping zigbee compatibility in future products, but them making moves like this doesn't give me much faith.
