I guess, but I don’t see how much they can really influence Telegram without any stake in the app itself. They only seem to have a deal for cloud-hosting with the TON Foundation, a non-critical part of the app, and even that appears to be non-exclusive. So if Tencent tries to force a bad decision onto Telegram, what’s stopping them from severing ties and moving everything over to another provider?
Of course, we don’t know what the situation will be like in the future, but at this present moment, I don’t think Telegram’s security has been breached by this. (Also I think you triple-posted this comment)
I’d be interested to know what the actual speeds will be outside of these pilot cities, and internationally. I’ve seen 10Gbps plans being advertised in my country recently, but they hide the fact that the international speeds are around 2 Gbps. (Still pretty fast, but definitely not worth the cost!)
A better question, actually: Who’s the target audience for this? Unless you routinely transfer terabytes of data daily, I don’t see why you would need anything more than 1 or 2 Gbps - and if you do need to transfer that much data, wouldn’t it be more cost-effective to lease dark fibre instead?
