BCash has full support on their platform, but no sign of Segwit. Is this going to be yet another BitPay situation where just because assholes as Roger Ver have a stake in these companies they can somewhat dictate their roadmap?
Everything he doesn't have as stake in swiftly upgrades to allow Bitcoin to scale as fast as possible, and unfortunately, I do think that you're right in this specific case. Blockchain.com could very well be the next BitPay.
60% of the industry is still using legacy format addresses, and while it's completely optional whether you support SegWit or not, you should at all times do what's the best for Bitcoin as the center of everything related to crypto.
