There's plenty of advertisers who have blogged about "My emails to Twitter stopped getting answered" around the time of the 75% layoffs. This is well documented.
What do you want the advertisers to do? To just keep giving money to Twitter even when all their contacts have disappeared? There's some pretty basic behaviors that have nothing to do with politics here that Twitter is failing at.
To say that ad sales has to be a manual, high touch channel is simply wrong. Perhaps you have staff on hand for large accounts, but why would e-commerce drop shipping headphone company #7 need to talk to a human?
Disney is most interested in making sure that Mickey Mouse / Winnie the Pooh / Zootopia is not accidentally shown next to furry porn. Southwest doesn't want its ads shown next to airplane disasters. Kellogs doesn't want "Itsssss GREAT" being shown next to the Ukrainian War.
As I said before: you can't predict the "X is being shown next to Y, please stop that" problem. Its impossible to predict X, its impossible to predict Y. You just gotta have email lines with these big companies and promptly issue your programmers / machine learning / data scientists the new algorithms to keep advertisers happy.

Twitter is 100% the grounds where furry porn, Airplane Disasters, and Ukrainian War disasters are constantly being discussed and shared. Advertisers want protection of their brand, despite the online discourse.
When the tools aren't working as expected, the advertisers then emailed Twitter's API teams. All of those teams have been dismantled, the executives have been fired. With no one left to contact, the advertisers have begun to leave.
Feature velocity for users. Not customers. Also, the deprecation of APIs strongly intimates Twitter Blue was a failure.
... and has driven away, or may drive away, many of the core content providers for their network effects. People who buy a third party client for twitter are generally not casual users. I reached out to a few friends I would consider 'posters' a couple of journos, a couple of 'personal brand' advertiser types... all of their twitter engagement is way down .. from both sides of the conversation. Two of them are now in a 'mostly I just post now' mode. Having conversations has become to hard. The other two are struggling along but they've had to cut way back, one said 'It was like I was building a house with a nailgun, but it got taken away and someone handed me a rock.'
It took me two days without tweetbot to realize it was was one of the only things that kept me actually using twitter. Finally causing me to mothball my account and throw up a personal mastodon install and start re-finding my personal follows there (I'm at about 50% of my list, but i'm finding that mostly what I'm missing is retweets from a few degrees out). My feed's incoming posts per hour are certainly down from twitter by about 60% but I was honestly expecting much lower numbers.
Onboarding is a PITA. With Twitter ceding the ground, this could be a real differentiator. Hell, you could build a licensing component paid to the servers.
It won't help you, currently or maybe ever, pick a server, but it's a great client even in it's beta form.
I mean, yeah? If someone fired all my contacts at a company and didn’t return my emails as my revenue dropped as a result of their changes I would also stop paying them?
It's gone from a break even company to financial ruination.
Twitter is shutting down data centers and offices. Elon Musk has single handedly collapsed the company.
Twitter will shortly be either bankrupt or personally funded by Elon Musk's bank balance by the end of the year.
Twitter has functioned fine after massive layoffs, and feature velocity has only accelerated. Too many developers have an inflated sense of self importance
