Stop that.
Why shouldn't people who want to know about privacy learn that BlackHatCoiner and o_e_l_e_o were hired by a custodial blockchain analysis company? This warning can't be repeated enough after the years they spent camping this topic in order to scam newbie Bitcointalk users out of their coins and data.
OK, if the Wasabi coordinators have those "weaknesses" in their system, what can the developers do to address them?
What "weaknesses" are you talking about?
So, remember people. Wasabi is completely trustless software, as long as you already have private coins, trust another person to join your coinjoin, and deliberately blacklist yourself on every coordinator you connect. Trustlessness on steroids.
You said "and" but you meant "or" instead -
ANY ONE of these three methods allow the attack target to drain the attacker's wallet,
so yes, it's trustlessness on steroids 
There's always a small risk of getting Sybil attacked; it's just the way coinjoins are constructed. But, no, we have Mr. Absolute Truth here harassing anyone who dares to claim that Wasabi might not cure cancer.
Okay why can't you prove it then? You keep repeating this claim, but you haven't come up with any methods that would allow you to simultaneously exploit the trustless protocol in 3 different ways:
Your "solutions" don't protect you against a malicious coordinator
Why wouldn't my solutions protect me? Explain how I can still be Sybil attacked if I use the methods I described to you. Start with method 1, explain how the malicious coordinator could defeat it, then go on to method 2, explain how the malicious coordinator could defeat it, then go on to method 3 and explain how a malicious coordinator could defeat it.
Thanks to its design, the WabiSabi protocol is completely invulnerable to a Sybil attack and you've provided absolutely no evidence or argument otherwise.
