The dongle still works. They reached market saturation with people who just want a dongle. They can’t realistically be expected to produce these forever.
Edit
Classic Lemmy. Point out that these are not charities and companies can’t keep producing niche products that you aren’t buying but maybe potentially want to buy someday and get thrown down votes. Down votes without a response tell me you’re just butthurt about the truth.
Sorry folks whether you like it or not it’s the truth. Companies like to sell things and if these were actually being bought enough to make a profit they wouldn’t be discontinued. Your TV probably has this feature built in now. Want another? Buy it second hand, the market is absolutely flooded with these second hand because they’re just collecting dust in cabinets. If Google kept making these they’d just end up as unsold stock in a landfill.
Your existing chromecast dongle will continue to connect because Google needs chromecast the protocol to continue to work to compete with Apples Airplay. It’s the same reason the Chromecast Audio dongle continues to work 5 years after it’s end of life.
If you want to make sure you have them forever buy up your local second hand stock but otherwise no one has given a convincing argument why these need more e-waste getting produced at the factory.
