So much of this stuff is pure conjecture, but I'll toss an idea out.

There's a focus on syllables, so I start there:

7, 7, 6, 5, 6, 10, 9 for each line, respectively

Line 1 is missing a syllable. Line 7 has an extra.

Add and reduce? 7 + 7 + 6 + 5 + 6 + 10 + 9 = 50; 5 + 0 = 5

Ok, if 5 is the key, go back and look at the line with 5 syllables. Poisoned frogs? Is the idea that Telegram is poisoning the frogs with frogs referring to anons using the platform? If so, how? It can't be content alone. It has to be a function of the platform. Telegram collects IP and a phone number to register an account. You also have to give it significant permissions to access files and smartphone functions for it to work properly. If it's collecting more than it advertises, and that info that could be seen as poisoning.

A quick excerpt from the Wiki (I know, not a source, but it's cited within to courses like the Financial Times and TechCrunch. Use your discernment.)

Telegram was launched in 2013 by the brothers Nikolai and Pavel Durov. Previously, the pair founded the Russian social network VK, which they left in 2014, saying it had been taken over by government.[31] Pavel Durov sold his remaining stake in VK and left Russia after resisting government pressure.[32] Nikolai Durov created the MTProto protocol that is the basis for the messenger, while Pavel Durov provided financial support and infrastructure through his Digital Fortress fund.[33] Telegram Messenger states that its end goal is not to bring profit,[34][35] but it is not structured as a non-profit organization.[36]

Telegram is registered as a company in the British Virgin Islands[9] and as an LLC in Dubai.[37][38] It does not disclose where it rents offices or which legal entities it uses to rent them, citing the need to "shelter the team from unnecessary influence" and protect users from governmental data requests.[39] After Pavel Durov left Russia in 2014, he was said to be moving from country to country with a small group of computer programmers consisting of 15 core members.[32][40] While a former employee of VK claimed that Telegram had employees in Saint Petersburg,[41] Pavel Durov said that the Telegram team made Berlin, Germany its headquarters in 2014,[42] but failed to obtain German residence permits for everyone on the team and moved to other jurisdictions in early 2015.[41] Since 2017, the company has been based in Dubai.[43] It has a complex corporate structure of shell companies to be ahead of government subpoenas.[44]

So, we've got Russian developers who have a pattern of getting their products captured by Russian FSB and compromised. And we have a chain of really shady shell corporations to hide who owns them and where they operate. If this organization is operating like FB and spying on everything you do on your phone and hijacking your microphone as well, it could be a particularly poisonous frog.

Anyway, that's my guess and the path I took. I'll look forward to seeing the correct answer later!
