Silicon Valley protests against lucrative technology companies continued over the weekend as campaigners visited the home of Google Ventures partner Kevin Rose, where they held up a sign calling him a "parasite" and distributed leaflets with the same message. 

Rose posted a photo on Instagram of what he said was a flyer distributed to his neighbours. 

"As a partner venture capitalist at Google Ventures, Kevin directs the flow of capital from Google into the tech start-up bubble that is destroying San Francisco," reads the flyer. "The start-ups that he funds bring the swarms of young entrepreneurs that have ravaged the landscapes of San Francisco and Oakland.

The flyer claims that each new tech corporation set up in Silicon Valley creates a wave of techies who on average earn four times more than a normal service worker. 

"We are the ones who serve them coffee, deliver them food, suck their cocks, watch their kids, and mop their floors," the flyer continues. "Nearly all of them are just like Kevin Rose and we are tired of this miserable and untenable situation."

In a separate attack on the Silicon Valley tech community last week, protesters blockaded and vomitted down the windshield of a Yahoo shuttle bus travelling from Oakland to Yahoo's headquarter's in Sunnyvale. 

Demonstrators waved signs that said, "Love the Bay, Block the Bus" and "Capital is the Driver, Gentrification is the Vehicle, Techies on the Bus." 

Google, Apple, Facebook and Yahoo, use corporate shuttle buses to ferry armies of staff from their homes to company headquarters in cities such as Mountain View, Palo Alto, and Sunnyvale, 30-40 miles further south of San Francisco.

The buses have become a symbol of wealth, disparity and gentrification in the San Francisco Bay Area, heckled and "booed" on an increasingly regular basis, particularly by the large homeless population in San Francisco. 

The tech companies claim that one bus is more efficient than 30 cars but the protesters don't appear to be showing any sign of backing off.

One "GBUS", carrying Google employees from Oakland to Mountain View, even had its window smashed in earlier this year. 

Alastair Mitchell, the British entrepreneur that co-founded enterprise collaboration platform Huddle, argues that the protests are no different to what happened during the Occupy London movement that took place in 2011-12. 

"Tech is obviously the most valuable and high-net-worth game in town," he told Techworld at Huddle's San Francisco office. "They don’t have finance doesn’t really exist, but tech does. I’d say it’s part of the same global movement."

Mitchell added: "The finance community were a bit kind of 'screw you' but the tech community are making an effort to show they’re giving more back. A lot of the big tech companies spend time and money on charitable giving and trying to improve welfare, whether it’s free lunches in schools or bike schemes."

On the other side of the Atlantic, property prices in Shoreditch, East London, where much of the UK's technology sector is clustered, property prices have risen in the same way that they have in Silicon Valley, forcing many people to relocate their homes and busiensses.   

While London’s best-paid tech workers, some of whom are on six and even seven figure salaries, have gone relatively unscathed to date, this could change as those in the industry start to command even higher salaries.
