Let me respond:
"not blockchain, so it already has a big minus in my mind" - Not IOTAs problem. Your bias.
"This leads to the significant number of vulnerabilities in IOTA hash function." - Teoretical volnerabilities outside of real world. Bitcoin has those too.
"danger of new critical vulnerabilities remains" - Like with any technology?
"fundamentally unable to do generalized smart contracts" - Many currencies dont. Thats not a flaw.
"brings more harm than benefit for the consumers" - Pls specify. You didnt mention any.
somehow its funny to watch all these Tom, Dick & Harry web-crypto-"experts" spreading fud about IOTA, while at real world big players like Bosch, Volkswagen, Innogy, Foxconn ... already cooperating with IOTA. This IoT-future is unstoppable - and in a few years no one gives a sh.t to lame, bloated blockchains and their moldy fanboiz.
UD is good :) but this post is full of logical faults, bad reasoning and misunderstanding of technology.
"in a few years no one gives a sh.t about blockchains" - More than few years :)
