Given the fact that a huge portion of these mining gears are sold to newbies who abuse the use of SSH by over clocking their gears and doing things they don't understand, it has probably created a lot of work load on their support team, let alone the numbers of gears which are under warranty and they have to fix/replace because people want to hash at 50% or 100% more than the default hashrate.
I was upset when I first updated my miners to the latest firmware , but then one member here (forgot who was , but credit goes to him) pointed out a similar point to what I have mentioned above, and after giving it a second thought, I can't seem to blame them for it.
anyway way if you have a lot of gears and you really need SSH access, i saw a trusted guy on Telegram selling a a plug and play PI with a script that should unlock all your gears over night, you basically just have to plug it into your network and go to bed, later on you have full SSH access to all your gears, can't remember how much he sells it for, but i think Taserz or Scott would know because they are more active on telegram than I am , and if anyone is interested I can ask for them or invite them to the Telegram group.
