Then why did you make this claim quoting the story?
LOL, they send in SWAT teams for twitch streamers.
The fact is they sent the SWAT team in not because they were going after users, they thought they had a house full of heroin dealers which make such raids extremely high risk for the officers serving the warrants since they tend to be very well armed and very willing to use those arms to resist being caught.
Now, back to your own cited article.
The home of Tuttle and Nicholas seems to have fallen short of the heroin dealer den police likely expected to find. According to the Chronicle , police recovered from the scene several guns and “small amounts” of marijuana and white powder that later tested positive for cocaine. Police have not said whether the guns were legally purchased, and the exact amounts of marijuana and cocaine found have not been publicly released. Though the household’s suspected heroin stash served as the main legal basis for the raid, there is so far no indication that officers found any of the drug.
On Wednesday, Acevedo released parts of the search warrant that allowed for the raid. According to the affidavit, the narcotics squad had been investigating the house for two weeks when they enlisted a confidential informant to go into the house and attempt to buy drugs (Acevedo said at a press conference Thursday that police received a tip earlier in January from an anonymous caller, who said her daughter had been inside the house doing heroin and that there were guns inside).

At that point investigators did not know the names of anyone who lived inside the house, only that there was a man inside who looked to be around 55 years old. On Sunday, the officers met with the informant, gave him some money, and sent him inside the house to try to buy drugs. He returned with “brown powder” that later tested positive for heroin.
According to the affidavit, the informant said he bought the powder from the middle-aged man, who called it “boy,” a street name for heroin. The informant also said that the man carried a gun, and that there was more of the brown powder at the house, “packaged in a large quantity of plastic baggies.” The author of the affidavit wrote that the informant had “proven to be credible and reliable on many prior occasions” and he asked a municipal court judge “to enter the suspected place and premises without first knocking and announcing the presence and purpose of the officers executing the warrant.” As probable cause for the no-knock raid, the investigator wrote that because there was heroin inside and the man there was armed, it was reasonable to believe that the suspect would use the gun to defend himself or to buy time to destroy the drugs if he knew beforehand that police were going to enter the house. The order was signed at 1:30 p.m. on Monday. Within three and a half hours police had arrived at the house, armed and ready.
So, if we accept the facts as reported to be true the level of force was certainly reasonable based on the two week long investigation prior to the raid.
Once again the facts simply don’t support your claim that the officers simply “gunned them down”. Four of the cops were also shot.
