Why are there so many tech pauses?

Title. Like are these players just smashing their keyboards every 7 rounds?

It's to cover up the whole system.

You see, most pro players actually cheat, and riot knows and supports it. The admins aren't all used to working in this sort of cheating environment, so sometimes they install vanguard on the pcs by accident. When they do, the player gets flagged for cheating and they have to remove vanguard from the pc.

Riot tech sucks.

Could be many issues, for example in the 100 Thieves vs Havan Liberty match, Liazzi's keyboard layout was reverse a couple of rounds

EU production always when KR wins the round flawless to break their momentum cheap tactics

Yesterday zombs was playing without hearing the enemy ults pop so that's why it was soo many yesterday.
