It's categorically unfair, but everyone says it when the "teacher isn't looking": Tech companies are just riding the wave to get rid of low performers and troublemakers while they can. Signalling that you're part of that group (and I know it's unfair, I already said that) is unlikely to work to your advantage, in my view. It's a signal to the counterparty that they have leverage over you. It's going to attract people who want/need that leverage disproportionately. It probably will increase the raw number of contacts you make, but for the reasons above, I would avoid doing it until I crossed some threshold of "desperation".
