I believe that you have mis-read their comment - they aren't saying Solar Winds is "yet another startup", they're saying that SolarWinds is incorporating 3rd party technology (the so-called supply chain attack on their build) without vetting it. And, if we're being honest, those technologies probably are based off startup tech; SolarWinds purchases and incorporates startup companies (such as Vivid Cortex recently).
